ball-and-stick model 3D models with sticks to represent bonds and spheres to represent atoms.
tetrahedron a solid having four plane triangular surfaces; a triangular pyramid
tetrahedral molecule a molecule with a symmetrical shape, with one atom exactly in the center.
electron domain the space between atoms occupied by the electrons, often shown as a shaded region
electron domain theory also called VSEPR theory, the tendency for electron pairs to be as far apart from one another as possible.
pyramidal molecule when all the hydrogen atoms are located on one side of a single atom.
bent molecule describes a molecule with two bonded pairs and two lone pairs where the two bonded pairs are on the same side of the central atom.
linear molecule when all the atoms are in a straight line
point molecule when there are no bonded pairs, only lone pairs
triagonal planar when the three electron domains spread out into the shape of a flat triangle
space-filling model 3D Model where there is no space between atoms. Instead, bonded atoms are shown slightly overlapping.
receptor site theory molecules have specific shapes that will fit only certain receptor sites
gas the form of matter that conforms to the size and shape of its container

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
